Hello,

I have got a problem when loading 'obj'-files:

* I load 'test.obj'

        v -10 0 -10
        v 10 0 -10
        v 10 0 10
        v 0 0 15
        v -10 0 10

f 1 2 3 4 5

via

         // add modells scaled by world scale
          for (i=0; i<app->numModells; i++)
          {
              dcs=pfNewDCS();
              pfNodeName(dcs,"modell dcs");
              pfDCSScale(dcs, app->worldScale);
              pfAddChild(globals->scene,dcs);
---> loade=LoadFile(app->modells[i],NULL);
              if (!loade)
              {
                  fprintf(stderr,"\nCouldn't find modell %s\n\n",app->modells[i]);
                  exit(EXIT_FAILURE);
              }
              pfNodeName(loade,app->modells[i]);
              pfAddChild(dcs, loade);
          }

* when I print the scene using

        sprintf(fname,"lightning.tree.%d",fcount++);
        f=fopen(fname, "w");
---> pfPrint(globals->scene, PFTRAV_DESCEND, PFPRINT_VB_DEBUG, f);
        fclose(f);

I get:

This is not what is in 'test.obj'. Any hints?
